"It was really weird for me," Orioles first baseman Aubrey Huff said. "I've never been more amped up or nervous to play an opening day in my life. I was really geeked up for this one."

Angelos addressed the team in the clubhouse before the game. It was the first meeting with the owner for many of the team's established players.

At the introduction of lineups, and with each subsequent introduction thereafter, Maryland native Teixeira was heavily booed for choosing the rival Yankees over his hometown team.

After Biden's ceremonial first pitch, the Orioles promptly put 14 hits and 10 runs on the board against a Yankees club picked by many analysts to win the division.

For a team predicted to finish fifth, with a sub-.500 record for a 12th straight season, it was an exciting opener.

The crowd was the largest opening-day gathering in ballpark history, and it offered some hope for a team that has seen more than its fair share of empty seats in the last two years.

"Seeing the big crowd, that's awesome," Huff said. "If we had that every day, there's no telling what you can do. As players, seeing that, it helps you lock down and focus. It's a lot more fun when you have a crowd like that."

ORIOLES 10, YANKEES 5: CC Sabathia was smacked around for eight hits and six earned runs in 4 1/3 innings in his Yankees debut. The top three hitters in the Orioles lineup -- Brian Roberts, Adam Jones and Nick Markakis -- combined to go 8-for-11 with four RBIs and seven runs.
